Rock Band 1 & 2 Problems

Ok, I'm having a few problems with the 1st and 2nd Rock Band games. The 1st game won't sync with my guitar controller (it's a guitar hero controller, works fine with Rock Band 3, LEGO Rock Band) The 2nd game however wont' boot (using CFG Loader v70) It will load to a weird green screen that will flicker from green vertical lines, green & white static (similar to old TV's that has no reception), to a greenish health screen. and the screen has a thick black box around the edge like its been zoomed out abit. It's a PAL console and PAL iso (may have patched it to PAL from NTSC, I'm unsure)
